Definitions
- FIG. 2 shows a sectional view along the line II—II from FIG. 1 ;
- Axial forces acting on the traction area 28 of the variator disk 14 are applied to the support disk 16 via the bearing surfaces 20 , 22 and also via the collar 30 and the mating section 31 .
- the support disk 16 rests in the axial direction on a step of the shaft 12 .
